Asbestos, once hailed as a “miracle mineral,” has evolved into a persistent and insidious threat to public health. Originally celebrated for its resistance to heat, fire and chemicals, asbestos was widely used across various industries from construction to automotive manufacturing for many years. However, the same properties that made it so valuable have also made it a lingering danger.

According to a recent report[1], 38% of Americans have been exposed to asbestos in high-risk industries, while 47%, including women and younger generations, have experienced indirect exposure through family members.

Unfortunately, many still view asbestos as a problem of the past, ignoring the fact that its effects can lie dormant for decades before manifesting in serious health conditions. Asbestos is nothing short of a ticking time bomb continuing to endanger lives, and the issue of industries evading safety regulations persists.

The rise of asbestos & a well-orchestrated cover-up

Asbestos became an integral part of the industrial landscape during the 20th century, and its applications were extensive, ranging from use in boiler systems and insulation to automotive parts, textiles, cement, and even materials included in the space race. It was woven into the very fabric of American industry, found in many homes, factories, ships, vehicles, public facilities, and just about everywhere else imaginable.

As use became widespread, so, too, did knowledge of potential dangers. Many workers were developing respiratory illnesses, yet the industries that relied on asbestos were quick to cover this up. Even amid mounting evidence, drastic measures were taken to protect profits, including industry execs hiring scientists to downplay the dangers and creating front groups like the Asbestos Information Association (AIA) and the Industrial Hygiene Foundation (IHF). These organizations, masquerading as independent entities, produced misleading reports and testimony.

The industry’s actions set a dangerous precedent that was also evident in the smoking and lead sectors at the time, and continues to influence certain industries even today, especially in chemicals and fossil fuels where corporate greed can sometimes overshadow safety concerns.

Asbestos remains a modern-day threat

The Environmental Protection Agency’s (EPA) was eventually successful in restricting use during the late-1980s. But, despite this, and the agency’s more recent ban on chrysotile asbestos, asbestos use persists, and its former legacy also remains.

Fibers are still present in aging infrastructure, and symptom latency offers a deceptive sense of security. While laws mandate the safe handling of asbestos during renovations or demolitions, they do not require the immediate removal of asbestos-containing materials (ACMs), particularly if they’re able to remain tucked away. Many individuals and organizations also attempt to cut corners in order to save on costs.

All of these factors combined can only mean one thing – asbestos remains a very real threat to public health, and it isn’t going away anytime soon.

Devastating health effects

Mesothelioma is perhaps the most well-known asbestos-related disease. This develops when asbestos fibers lodge in the lining of the lungs, chest, or abdomen, causing chronic inflammation and, eventually, cancer[2]. Beyond mesothelioma, asbestos is also the leading occupational risk factor for lung cancer and other respiratory diseases such as asbestosis and pleural thickening.

Many asbestos-induced illnesses involve the lungs, but fibers can quickly travel to other areas of the body as well, often leading to cancers of the digestive system, including throat, stomach, colorectal, colon[3], and ovarian cancers, among others.

The importance of screening & awareness

Alarmingly, only 8% of Americans undergo regular health screenings[4], leaving the majority of the public unaware of whether they have been exposed to asbestos or whether damage has occurred. This lack of awareness allows diseases to progress undetected, often until it is too late for treatments to be effective.

Catching these diseases in their early stages allows for more aggressive treatment options, which often improve one’s chances for survival and improve overall quality of life. Regular screenings, by way of a simple chest X-ray or lung function test, particularly for those who may have been exposed in the workplace or at home, can be lifesaving

Beyond the workplace: Protecting loved ones

The dangers of asbestos exposure extend beyond the workplace, affecting family members who may unknowingly be exposed secondhand. In 2021, the CDC reported an increase in mesothelioma rates among women, many of whom had no direct exposure to asbestos but were exposed through their loved ones who handled it on the job. This highlights the importance of education and preventative measures, not just for workers but for those they live with, including spouses and children[5].

The bottom line

Asbestos, once a celebrated innovation, remains a hidden hazard that continues to endanger public health. Despite increased awareness and regulation, the legacy of its widespread use persists, with many individuals unknowingly carrying the seeds of asbestos-related diseases. The hidden nature and symptom latency of asbestos has created a false sense of security for many, but the risks are very real and persist still today. By raising awareness, encouraging regular testing, and implementing stricter regulations, we can better protect ourselves and future generations.
